It felt like it needed to be a mountain.” The Hubble and Webb aesthetic is not the only approach taken by scientists or professional and amateur astrophotographers. It is popular among photographers on the ground, partly, according to public science communicator Dylan O’Donnell, because using a narrowband approach helps to avoid problems of light pollution. A camera at ground level will be inundated by light from buildings and streets.
There are many different potential combinations of wavelengths and filters, all of which result in different ways of displaying the data — as well as different aesthetic experiences.
